664875 ÷ 49 
We want to figure out the number of times 664875 can be divided by 49.

Going ahead to step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 49

Moving on to step 2:
49 goes into 66 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 66 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 49

On to step 3:
When dividing 174 by 49, we get 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 147 from 174 to get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 49

Going ahead to step 4:
The number 49 fits into 278 5 times, leaving a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Deduct 245 from 278 and we're left with 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 49

Going ahead to step 5:
When dividing 337 by 49, we get 6 with a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 1356.0
Subtracting 294 from 337 leaves us with 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 49

On to step 6:
When dividing 435 by 49, we get 8 with a remainder of 43.
The next digit of our result is 8. 
Result so far: 13568.0
If we take 392 away from 435, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 49 fits into 430 8 times, leaving a remainder of 38.
The next digit of our result is 8. 
Result so far: 13568.8
If we subtract 392 from 430, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
If we divide 380 by 49, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 13568.87
Deduct 343 from 380 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
49 goes into 370 7 times with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 13568.877
Deduct 343 from 370 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 13568.877, with a leftover of 0.0027.
